Optimizing Dubbo Routing and Load Balancing at Scale: Vivo's Practice
Vivo tackled high CPU overhead in large‑scale Dubbo deployments by disabling unused routers, caching routing results with BitMap intersections and epoch validation, optimizing weight calculations, and adding a grouping router, which together delivered over 100 % TPS gains for 20 k+ providers and cut CPU usage by roughly 27 %.
